Was at the WW1 fort on Mont Vully in Switzerland last weekend, looking at the old emplacements, and one thing struck me on the info boards: in the WW1 period, the Swiss army considered the following effective ranges for infantry armed with the G11 "Langgewehr": Single rifleman: 500m Sektion (50 men): 1000m Kompanie (200 men) or more: 1500m Maxim MG11: 2500m One inf emplacement for a reinforced company of 300 riflemen would have covered basically up to the lake, with the exception of a few bits of dead ground. At each emplacement are handy maps showing the areas covered by fire from the emplacement. Worth a visit. TBH, 300 riflemen in a fixed position who could all shoot reasonably well could put down 3000 rds per minute with no sweat, which might spoil your day somewhat. There's also an 8-MG emplacement in hand-hewn artificial caves that we happened to miss: Grottes de la Lamberta - Mont Vully - Position d'artillerie de la guerre 14-18 - YouTube Might drag some pictures off Google for illustration.
